The Kingdom of SiamOriginally published in Paris and Amsterdam in 1691 as Du royaume
du Siam, de La Loubère's description of 17th century Siamese
civilization is comprehensive, well-organized, and extremely accurate.
Although he served as a French diplomat in Siam for only four months,
in 1687, de La Loubère's accounts of physical geography, manners
and customs, social and administrative structure, and religion remain
useful today for our understanding of Thai culture and society. His careful
observations, intelligent use of the accounts of others, and objectivity
make this book universally regarded as the finest work on 17th century
Thailand.
